Frost Peach
Pollination & Compatibility Guide

Frost is a self-fertile peach with viable pollen and Group 3 bloom. The source notes strong resistance to peach leaf curl, which can be useful in wet spring districts. That disease trait is separate from pollination: Frost needs no partner for its own set but can supply a pollen-sterile neighbour only when open flowers overlap. A disease-resistant name does not imply that blossom avoids frost injury.

No cultivar-specific chill number is stored in our current record, so compare local trial experience rather than assigning a generic peach figure. Rain during early growth still warrants canopy inspection even where leaf curl pressure is lower. After fruitlets form, thin a crowded crop and maintain renewal shoots for next year's bearing wood. Leaf-curl resistance cannot compensate for poor light, excessive load or a cold-air trap at bloom.

Frost can be trained as an accessible open-centre tree with regular removal of shaded older wood. Select a peach-compatible rootstock for the site's drainage and replant history; do not transfer Myrobalan, Marianna, St Julien or Torinel from an adjacent plum block. A stock that tolerates a heavier soil may be worth more than a smaller tree on a poorly matched root system. Confirm the graft and disease programme with the nursery and local adviser.
